Definitions

  • the present invention relates to a propulsion bay intended to be transported, at least temporarily, in a space launcher, comprising an adapter for cooperation with at least one on-board system, at least temporarily, on the bay, the system comprising a power supply.
  • space launchers are known for the transport, at least temporarily, of at least one space 16 on which equipment 6 or 7 and propulsion means 230 are fixed, cf. EP 0 665162 .
  • Box 16 comprises an adapter 3, 4 for cooperation with at least the system 6 on board 16, at least temporarily.
  • the embedded system 6 generally forms an artificial satellite.
  • the stages 21 and 22 are first fired (E1) for the launch of the launcher 2, and then only the stage 22 is retained (E2) for the output of the Earth's atmosphere (the stage 21 then separates from floor 22).
  • the cap 13 is then separated (E3) of the launcher 2 because it is heavy (typically 1.7 tons) and now useless (at an altitude of about 69km, there is no atmosphere), then the floor 23 takes (E5) the relay of the propulsion after a step (E4) of separation from the stage 22.
  • the system 6 will then be separated from the box 16, once the motor 230 of the cut stage 23 (E6), and put into orbit.
  • the motor 230 of the stage 23 is a motor with liquid propulsion, and offers little flexibility of use (any interruption of its operation is indeed final). Because of the engine 230 with chemical fuels, the launcher payload 2 (that is to say the equipment intended to fulfill a specific mission (including the systems 6 and 7) and that carries the launcher 2 (and in particular the box 16)) is limited and can only be injected into one orbit.
  • the invention overcomes at least one of these disadvantages.

  • the invention allows a pooling of resources in the launcher, because it allows the use of the power supply of a system embedded on the bay for the power supply of the aforementioned electric motor of the bay: the mass gain on the bay can thus be transformed into an increase of the payload.
  • the invention thus makes it possible to increase the payload of the launcher, and in particular to increase the mass of the systems embedded on the bay, in particular the mass of the artificial satellites.
  • FIGS. 3 to 14 schematically represent a possible embodiment of a propulsive bay 1 according to the invention.
  • the bay 1 is intended to be housed in a launcher 2.
  • the bay 1 is additional and is housed in the launcher 2, at least temporarily, at a box 16. No adaptation of the launcher 2 is necessary for the bay housing 1.
  • the bay 1 therefore has dimensions adapted for its housing in the launcher 2: typically a diameter of a few meters and a height of the order of one meter.

It is therefore understood that there is a pooling of resources in the launcher, because of the use of the power supply of a system embedded on the bay for the power supply of the launcher. aforementioned electric motor of the bay: the mass gain on the bay can thus be transformed into an increase in the launcher payload, including an increase in the mass of embedded systems.
  • the power supply 9 of an on-board system is connected, by an electric power transfer link, to the electric motor 10 of the rack 1 via an electrical transformer T, either directly or via a battery B of the bay, for example placed in the box 126.
